  1. enumFrom :: Enum a => a -> [a]

    ghc-internal GHC.Internal.Enum

    Used in Haskell's translation of [n..] with [n..] = enumFrom n, a possible implementation being enumFrom n = n : enumFrom (succ n).

    Examples

    • enumFrom 4 :: [Integer] = [4,5,6,7,...]
    • enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound ::
      Int]

  2. enumFromThen :: Enum a => a -> a -> [a]

    ghc-internal GHC.Internal.Enum

    Used in Haskell's translation of [n,n'..] with [n,n'..] = enumFromThen n n', a possible implementation being enumFromThen n n' = n : n' : worker (f x) (f x n'), worker s v = v : worker s (s v), x = fromEnum n' - fromEnum n and

    f n y
    | n > 0 = f (n - 1) (succ y)
    | n < 0 = f (n + 1) (pred y)
    | otherwise = y
    
    

    Examples

    • enumFromThen 4 6 :: [Integer] = [4,6,8,10...]
    • enumFromThen 6 2 :: [Int] = [6,2,-2,-6,...,minBound ::
      Int]

  3. enumFromThenTo :: Enum a => a -> a -> a -> [a]

    ghc-internal GHC.Internal.Enum

    Used in Haskell's translation of [n,n'..m] with [n,n'..m] = enumFromThenTo n n' m, a possible implementation being enumFromThenTo n n' m = worker (f x) (c x) n m, x = fromEnum n' - fromEnum n, c x = bool (>=) ((x 0)

    f n y
    | n > 0 = f (n - 1) (succ y)
    | n < 0 = f (n + 1) (pred y)
    | otherwise = y
    
    
    and
    worker s c v m
    | c v m = v : worker s c (s v) m
    | otherwise = []
    
    

    Examples

    • enumFromThenTo 4 2 -6 :: [Integer] =
      [4,2,0,-2,-4,-6]
    • enumFromThenTo 6 8 2 :: [Int] = []

  4. enumFromTo :: Enum a => a -> a -> [a]

    ghc-internal GHC.Internal.Enum

    Used in Haskell's translation of [n..m] with [n..m] = enumFromTo n m, a possible implementation being

    enumFromTo n m
    | n <= m = n : enumFromTo (succ n) m
    | otherwise = []
    
    

    Examples

    • enumFromTo 6 10 :: [Int] = [6,7,8,9,10]
    • enumFromTo 42 1 :: [Integer] = []

  5. enumFromN :: Num e => Comp -> e -> Sz1 -> Vector D e

    massiv Data.Massiv.Array

    Same as enumFromStepN with step dx = 1. Related: senumFromN, senumFromStepN, enumFromStepN, rangeSize, rangeStepSize, range

    Examples

    >>> import Data.Massiv.Array
    
    >>> enumFromN Seq (5 :: Double) 3
    Array D Seq (Sz1 3)
    [ 5.0, 6.0, 7.0 ]
    
    Similar:

  6. enumFromStepN :: Num e => Comp -> e -> e -> Sz1 -> Vector D e

    massiv Data.Massiv.Array

    Enumerate from a starting number x exactly n times with a custom step value dx. Unlike senumFromStepN, there is no dependency on neigboring elements therefore enumFromStepN is parallelizable. Related: senumFromN, senumFromStepN, enumFromN, rangeSize, rangeStepSize, range, rangeStepM

    Examples

    >>> import Data.Massiv.Array
    
    >>> enumFromStepN Seq 1 (0.1 :: Double) 5
    Array D Seq (Sz1 5)
    [ 1.0, 1.1, 1.2, 1.3, 1.4 ]
    
    >>> enumFromStepN Seq (-pi :: Float) (pi/4) 9
    Array D Seq (Sz1 9)
    [ -3.1415927, -2.3561945, -1.5707964, -0.78539824, 0.0, 0.78539824, 1.5707963, 2.3561947, 3.1415927 ]
    
    Similar:
    • Prelude.enumFrom Similar to take n [x, x + dx ..], except that enumFromStepN is parallelizable and it only works for Num and not for Enum elements. Floating point value will be slightly different as well.
    • Data.Vector.Generic.enumFromStepN Similar in the outcome, but very different in the way it works.

  7. enumFromN :: Num e => Comp -> e -> Sz1 -> Vector D e

    massiv Data.Massiv.Vector

    Same as enumFromStepN with step dx = 1. Related: senumFromN, senumFromStepN, enumFromStepN, rangeSize, rangeStepSize, range

    Examples

    >>> import Data.Massiv.Array
    
    >>> enumFromN Seq (5 :: Double) 3
    Array D Seq (Sz1 3)
    [ 5.0, 6.0, 7.0 ]
    
    Similar:

  8. enumFromStepN :: Num e => Comp -> e -> e -> Sz1 -> Vector D e

    Array D Seq (Sz1 5)
    [ 1.0, 1.1, 1.2, 1.3, 1.4 ]
    
    >>> enumFromStepN Seq (-pi :: Float) (pi/4) 9
    Array D Seq (Sz1 9)
    [ -3.1415927, -2.3561945, -1.5707964, -0.78539824, 0.0, 0.78539824, 1.5707963, 2.3561947, 3.1415927 ]
    
    Similar:
    • Prelude.enumFrom Similar to take n [x, x + dx ..], except that enumFromStepN is parallelizable and it only works for Num and not for Enum elements. Floating point value will be slightly different as well.
    • Data.Vector.Generic.enumFromStepN Similar in the outcome, but very different in the way it works.

  10. enumFrom :: Enum a => a -> [a]

    protolude Protolude

    Used in Haskell's translation of [n..] with [n..] = enumFrom n, a possible implementation being enumFrom n = n : enumFrom (succ n).

    • enumFrom 6 :: [Int] = [6,7,8,9,...,maxBound ::
      Int]
